Give it another week maybe the rumors are true and BD just needs new BIos or some kind of Update to work Correctly but if not i still say give Bulldozer a try looking at Review is different than experiencing it yourself

Do you already own a 990FX board? If so, I'd say hold out and see what happens with real users of Bulldozer in the next week or two. If you have to buy RIGHT NOW, go for Thuban (again assuming you already have the board).
